Nigra ; alis violaceis, basi late fiavo-hyalinis. Long. 3 21-22 mm., $ 25 mm. Antennae black; the scape covered with very long black hair; the flagellum opaque, covered with a pale microscopic down. Head rather narrow ; except on the front it is thickly covered with long black hair. The vertex is not very shining and is sparsely punctured ; the front below the ocelli is smooth and shining; the lower part obliquely projects, is closely and distinctly punctured and with a furrow down the centre ; this oblique lower part is distinctly separated from the upper. Clypeus strongly punctured, except in the centre. Thorax thickly covered with black hair; it is closely and strongly punctured all over, except on the upper half of the mesopleurae behind. Wings fuscous-violaceous; the base to shortly beyond the transverse basal nervure and the first radial cellule fulvous-yellowish. Abdomen black, distinctly violaceous on the back, closely punctured and thickly covered with black hair. The $ has the mesonotum in the centre impunctate; its antennae are fuscous beneath; the punctuation of the thorax is stronger, closer, and more uniform ; the bypopygium is strongly punctured except at the apex : the wings are of a brighter violaceous tinge; the front is not excavated and there is a broad impunctate band below the ocelli; its fore spurs are rufous; the tarsal spines are of a brighter rufous colour.

Head rufous, thickly covered with depressed golden pubescence; the eyes slightly converge above and are there separated by a little more than the length of the fourth antennal joint, which is not much longer than the scape and distinctly shorter than the third. The ocelli are almost in a triangle and are close together ; the hinder are separated from the anterior by nearly the same distance they are from each other; from the eyes they are separated by a perceptibly greater distance than they are from each other. The apex of the clypeus is bluntly rounded; the mandibles have the teeth black ; the apical one is bluntly rounded ; the subapical is transverse at the apex, and is not separated behind. Pro- and mesothorax thickly covered with golden depressed pubescence, and more sparsely with fuscous hairs. The scutellum is not much raised above the mesonotum, and is rather flat; the post-scutellura |
